FIELD OF INVENTION

The present invention is generally directed to an ultrapolar telescopicelectrosurgery pencil with argon beam capability which is capable ofusing monpolar energy in a bipolar mode for cutting and coagulation andalso capable of using an ionized gas for cutting and coagulation.

BACKGROUND OF THE INVENTION

Electrosurgery uses an RF electrosurgical generator (also known as anelectrosurgical unit or ESU) and a handpiece with an electrode toprovide high frequency, alternating radio frequency (RF) current inputat various voltages to cut or coagulate biological tissue. The handpiecemay be a monopolar instrument with one electrode or a bipolar instrumentwith two electrodes. When using a monopolar instrument, a returnelectrode pad is attached to the patient and the high frequencyelectrical current flows from the generator, to the monopolarinstrument, through the patient to the patient return electrode pad, andback to the generator. Monopolar electrosurgery is commonly used due toits versatility and effectiveness. However, the excessive heat generatedwith monopolar electrosurgery can cause excessive tissue damage andnecrosis of the tissue because the return electrode positioned on theback of the patient causes high voltage and high RF energy to passthrough the patient.

In bipolar electrosurgery, active output and patient return functionsboth occur at the surgery site because both the active and returnelectrodes are contained in the bipolar instrument. Therefore, the pathof the electrical current is confined to the biological tissue locatedbetween the active and return electrodes. Although bipolarelectrosurgery enables the use of lower voltages and less energy thanmonopolar electrosurgery and thereby reduces or eliminates thelikelihood of tissue damage and sparking associated with monopolarelectrosurgery, it has limited ability to cut and coagulate largebleeding areas.

It is also common to use argon beam coagulators during electrosurgery.In argon beam coagulation (ABC), current is applied to tissue by adirected beam of ionized argon gas which causes a uniform and shallowcoagulation surface thereby stopping blood loss. However, argon beamenhanced cutting may also be performed using application of an ionizedargon gas.

At present, electrosurgery is often the best method for cutting andargon beam coagulation is often the best method for cessation ofbleeding during surgery. Surgeons typically need to switch between argonbeam coagulation and electrosurgery modes depending on what is happeningduring the surgery and what they need to achieve at a particular pointin the surgery such as cutting, or making incisions in tissue, orstopping the bleeding at the surgical site.

However, since surgical tools and devices currently available tosurgeons require switching between these two methods during the surgicalprocedure, there is a need for a surgical device or tool that enables asurgeon or user to utilize the best methods used for cutting andcessation of bleeding at the surgical site both separately and at thesame time, or simultaneously, in addition to being able to use themseparately. A telescopic electrosurgery pencil with argon beamcapability that includes an electrode blade assembly with argon beamcapability can provide a user or surgeon with safe, efficient,effective, and flexible ways to both cut and coagulate tissue duringelectrosurgery. In addition, the telescoping ability of an ultrapolartelescopic electrosurgery pencil can enable a user or surgeon to adjustthe length of the ultrapolar electrosurgery pencil to better accommodateaccessing different surgical sites.

SUMMARY OF THE INVENTION

The present invention is directed to a telescopic ultrapolarelectrosurgery pencil with argon beam capability that is capable ofusing monopolar energy in a bipolar mode for cutting and coagulationusing an electrosurgery blade and also using ionized gas for cutting andcoagulation thereby providing a user or surgeon with a variety of waysto perform cutting and/or coagulation of tissue during an operativeprocedure.

In one exemplary embodiment, the ultrapolar electrosurgery bladeassembly contained within the ultrapolar telescopic electrosurgerypencil of the present invention includes an ultrapolar electrosurgeryblade having a non-conductive blade with opposing planar sides, a narrowelongated top, a sharp cutting end, and an opposite non-cutting end, andboth an active electrode or active contact and a return electrode orreturn contact (note that the terms electrode and contact are usedinterchangeably throughout this specification) located on each of theopposing planar sides of the non-conductive blade, and a non-conductivehollow tubular member positioned over the narrow elongated top of thenon-conductive blade so that the non-conductive hollow tubular membercovers at least a portion of an active electrode/contact on one of theopposing planar sides of the non-conductive blade and at least a portionof a return electrode/contact on the other opposing planar side of thenon-conductive blade. This enables a gas supplied to the non-conductivehollow tubular member to be ionized as it comes into contact with theactive and return electrodes/contacts contained within thenon-conductive hollow tubular member thereby enabling both cutting andcoagulation of tissue without high voltage and high RF energy passingthrough the patient.

In another exemplary embodiment of the ultrapolar electrosurgery bladeassembly contained within the ultrapolar telescopic electrosurgerypencil of the present invention, a second non-conductive hollow tubularmember may also be included as part of the ultrapolar electrosurgeryblade assembly by positioning it adjacent to the previously describednon-conductive hollow tubular member that is positioned over at least aportion of both active and return contacts located on opposite sides ofthe electrosurgery blade. In this embodiment, the second non-conductivehollow tubular member may also be positioned and fixed over theelectrosurgery blade (but not necessarily positioned over both activeand return contacts on the electrosurgery blade) and the previouslydescribed non-conductive hollow tubular member may be supported in itsposition over at least a portion of the active and return contacts ofthe electrosurgery blade by seating it on a non-conductive shelf supportlocated on the electrosurgery blade. This enables the non-conductivehollow tubular member that is positioned over at least a portion ofactive and return contacts of the electrosurgery blade to bechangeable/replaceable if desired. Alternatively, the non-conductivehollow tubular member that is positioned over at least a portion ofactive and return contacts of the electrosurgery blade may also bepermanently attached to the second non-conductive hollow tubular memberand/or the non-conductive shelf support. The non-conductive hollowtubular member may include a slot which fits over the electrosurgeryblade and an opening located above the slot through which an ionized gascan project after coming into contact with the active and returncontacts of the electrosurgery blade contained within the non-conductivehollow tubular member.

An exemplary embodiment of the ultrapolar telescopic electrosurgerypencil with argon beam capability of the present invention includes ahandpiece member with a channel having first and second ends; a firstconductive hollow tube contained within the channel; a second conductivehollow tube contained within the channel; a hollow telescopic memberhaving first and second ends where the second end of the hollowtelescopic member is contained within the handpiece member; a thirdconductive hollow tube having a smaller diameter than the firstconductive hollow tube where the third conductive hollow tube iscontained within the hollow telescopic member and at least a portion ofthe first conductive hollow tube; a conductive cylindrical membercontained within the hollow telescopic member and at least a portion ofthe second conductive hollow tube; an ultrapolar electrosurgery bladepositioned within the first end of the hollow telescopic member wherethe ultrapolar electrosurgery blade includes a non-conductive bladehaving opposing planar sides, a sharp cutting end, and both an activecontact and a return contact on each of the opposing planar sides of thenon-conductive blade where the active contacts are connected to thethird conductive hollow tube and the return contacts are connected tothe conductive cylindrical member; and a non-conductive hollow tubularmember positioned on the ultrapolar electrosurgery blade so that itcovers at least a portion of an active contact on one opposing planarside of the non-conductive blade and at least a portion of a returncontact on the other opposing planar side of the non-conductive blade.

The channel within the handpiece member and the interior of the hollowtelescopic member together function as a smoke evacuation channel forevacuating smoke and/or debris away from the sharp cutting end of thenon-conductive blade where cutting and/or coagulation are taking placeduring operative procedures. The ultrapolar telescopic electrosurgerypencil with argon beam capability may also include a rotating/swivelmember connected to the second end of the handpiece to alleviate drag onthe end of the ultrapolar telescopic electrosurgery pencil and kinkingof a suction tube when a suction tube is attached to the end of theultrapolar telescopic electrosurgery pencil to evacuate smoke and/ordebris from the smoke evacuation channel.

The ultrapolar telescopic electrosurgery pencil with argon beamcapability of the present invention may also include additional elementsincluding, but not limited to, at least one support member for retainingthe first conductive hollow tube and the second conductive hollow tubewithin the channel of the handpiece, at least one support member forretaining the third conductive hollow tube and the conductivecylindrical member within the hollow telescopic member, a secondnon-conductive hollow tubular member positioned between, and connectedto, the non-conductive hollow tubular member and the third conductivehollow tube, and a non-conductive shelf support for supporting thenon-conductive hollow tubular member when positioned on the ultrapolarelectrosurgery blade.

The non-conductive hollow tubular member and the non-conductive blademay each comprise a ceramic. The non-conductive hollow tubular membermay include a slot which fits over at least a portion of a top of theultrapolar electrosurgery blade and an opening located above the slot oneach end of the non-conductive tubular member. Further, the hollownon-conductive tubular member may be positioned outside of the first endof the hollow telescopic member. In addition, one or both of the secondconductive hollow tube and the first conductive hollow tube may beinsulated about their exterior outer surfaces.

The exemplary embodiments of the ultrapolar telescopic electrosurgerypencil with argon beam capability of the present invention enable a useror surgeon to perform cutting with the sharp non-conductive tip of theelectrosurgery blade, cutting with the active and returnelectrodes/contacts of the electrosurgery blade, coagulating large areasof biological tissue by placing the electrosurgery blade on either ofits sides where both active and return electrodes/contacts are located,and cutting and/or coagulating tissue using ionized gas that projectsfrom the non-conductive hollow tubular shaped member that is positionedover active and return electrodes/contacts contained on theelectrosurgery blade. A particularly new and innovative feature of theultrapolar telescopic electrosurgery pencil with argon beam capabilityof the present invention is the ability of a user or surgeon tosimultaneously cut tissue with the sharp non-conductive tip of theelectrosurgery blade while coagulating tissue using ionized gas thatprojects from the non-conductive hollow tubular shaped member that ispositioned over active and return electrodes/contacts contained on theelectrosurgery blade. The ultrapolar telescopic electrosurgery pencilwith argon beam capability of the present invention provides a user orsurgeon with safe, efficient, effective, and flexible ways to both cutand coagulate tissue during electrosurgery. The ultrapolar telescopicelectrosurgery pencil with argon beam capability of the presentinvention is much safer for the patient than other electrosurgeryinstruments and methods due to the fact that high voltage and high RFenergy do not need to pass through the patient during electrosurgery. Inaddition, the telescoping ability of the ultrapolar telescopicelectrosurgery pencil with argon beam capability of the presentinvention enables a user or surgeon to adjust the length of theultrapolar pencil to better accommodate accessing different surgicalsites.
